EDWARD D. LEVY, OF SPRINGFIELD, MISSOURI.

STOP FOR RAILWAY-SWITCHES.

Application filed July 24, 1914.

To all whom it may concern Be it known that I, EDWARD D. LEVY, a citizen of the United States of America, a resident of Springfield, in the county of Greene, State of Missouri, have invented certain new and useful Improvements in Stops for Railway-Switches, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to a railway switchthereby securely holding the switch point to its proper position at such times.

Figure I is a top or plan view of a portion of a railway switch having a stop device embodying the features of my invention. Fig. II is an enlarged vertical section taken through the stop device, showing the switch point located adjacent to the stationary rail. Fig. III is a view similar to Fig. IIshowing the switch point separated from the stationary rail, and illustrating a modified form of the stop device.

In the accompanying drawings; A designates a stationary rail shown fitted to tie plates 1 secured to ties 2, and B designates a switch point movable toward and away from the stationary rail, said switch point being preferably slidably fitted to seats 3 formed on the tie plates. The switch point is preferably provided with the usual head 4, web 5, and case flanges 6.

C designates a stop device which is preferably fitted to the head, web and base flanges of the stationary rail A, and secured thereto by bolts 7 or other suitable means of fastening. The outer end portion of the stop device C is adapted to engage a base flange 6 on the switch point B to prevent the switch point from moving upwardly when it lies adjacent to the stationary rail, as shown in Fig. II. To prevent the switch point from moving downwardly, the stop device is preferably provided with an abutment face 9 adapted to engage the bottom face of the head 4 of the switch point. 10 designates an abutment extending upwardly Specification of Letters Patent.

from the stop device and adapted to engage the inner face of the head 4.,

The end face of the stop device is adapted to engage the web 5 of the switch point to limit the lateral'movcment of said switch point and to brace said point when it is shifted. toward the stationary rail A. It will be noted that the stop device is interlocked with and rigidly secured to the stationary rail A, and that the movable switch point, interlocked with the rigid stop device, is prevented from moving vertically and also stopped in the desired position by the stop device.

The different abutment faces of the stop device C, engaging the movable switch point, are so located that the switch point is prevented from canting or tilting when the head 4.- of the switch point is subjected to lateral pressure by the flange of a wheel. The importance of this feature will be apparent when it is understood that the switch points are usually held 01' secured at their ends only, and it frequently happens that the wheel flanges riding against the inner face of a switch point, cant or tilt the switch point topresent a corner of the head I to the tread of a wheel, thereby mutilating the switch point by wearing away one of its upper corners and sometimes bending one of its base flanges. In addition to being securely interlocked with the stop device, the switch point ispreferably fitted to a base flange of a stationary rail. one of the base flanges 6 of the switch point being fitted to and located between the bottom face of the stop device and the top face of the rail flange, as shown in Fig. II.

The stop device C, shown in Fig. III, is very similar to the stop device C, the only difference being that the stop device C of Fig. II is provided with a bottom abutment face which extends entirely across one of the base flanges 6, while the stop device C is formed with a narrower bearing face adapted to engage the inner portion of a flange 6.

I claim i 1. A railway switch comprising a stationary rail, a switch point movable toward and away from said stationary rail, the switch point being provided with a base flange, and a stop member, secured to said stationary rail, adapted to engage "the base flange of the switch point for the purpose described.

"'2 point being provided With a head, a web and a base flange; and a stop device fitted to the head, web and base flange of the stationary rail, adapted to interlock with said switch point-when the later lies adjacent to ange; and a stop devlce said stationary rail, the outer end portion of said stop device being adapted to engage the head, web and basefiange of said switch point.

4. A railway switch comprising a stationary rail having a base flange, a switch point movable toward and away from said stationary rail, said switch point being provided with a base flange, and a stop device secured to said stationary rail, the bottom face of said stop device being separated from the top face of the flange on said stationary rail so that the flange of said switch point may be moved to a position between and engaged with said faces.
